Definitions

  • Another object of this invention is to provide a conjugate spinnerette which is simple and easy to construct.
  • a further object of this invention is to provide a conjugate spinnerette which is made up of a plurality of longitudinally milled manifolds which are mounted in bores in a plate.
  • One embodiment of the present invention contemplates a conjugate spinnerette wherein a generally tubular manifold or insert is mounted in a bore in a support member.
  • the periphery of the manifold or insert is provided with a plurality of longitudinal grooves which serve as spinning orifices, these grooves being connected to the interior of the manifold.
  • a first spinning solution is forced through the manifold into the grooves while a second spinning solution is forced into the grooves from the exterior of the tubular manifold.
  • the two solutions exit from the grooves as conjugate or composite filaments.
  • FIGURE 1 is an enlarged, perspective view of a spinning device illustrating the principles of the invention and showing the construction of the device.
  • FIGURE 2 is a fragmentary sectional view showing the arrangement of the various elements of the apparatus.
  • FIGURE 3 is an enlarged end view of one of the inserts.
  • a generally tubular manifold or insert 11 is shown mounted in a bore 12 in a plate 13, the engagement of the periphery of the manifold 11 with the wall of the bore 12 being substantially a press fit.
  • the periphery of the manifold 11 is provided with :a plurality of spaced longitudinal grooves 16 (shown greatly enlarged in FIGURE 3) which extend to the face of the plate 13 to serve as spinning orifices, the
  • a central bore 17 in the tubular manifold or insert 11 is interconnected with the grooves 16 by a plurality of openings 13 which feed a spinning solution from the bore 17 to the grooves 16.
  • the openings 18 intersect the grooves 16 in a plane extending through the plate 13 parallel to the face thereof. In other words, the openings 18 intersect the grooves 16 at points where these grooves are closed by the wall of the bore 12 in the plate 13.
  • FIGURE 2 While one spinning solution is forced into the grooves 16 from the bore 17, another spinning solution is forced into the grooves 16 from the exterior of the manifold or insert 11. The arrangement for accomplishing this is illustrated in FIGURE 2.
  • a plurality of plates 20-23 are mounted against the United States Patent 3 ,176,343 Patented Apr. 6, 1965 plate 13 and are held in this stacked relationship by spaced bolts 27.
  • the plates 21 and 23 are provided with enlarged rectangular manifold openings 31 and t 33 respectively, which serve :as manifolds for the spinning solutionsthe opening 31 being closed by the plates 20 and 22 and the opening 33 being closed by the plates 22 and 13.
  • a first spinning solution fed from a source 34 flows through the manifold opening 33 and into the grooves 16 in the tubular manifold 11.
  • a second spinning solution fed from a source 35 flows through the manifold opening 31 and a pipe 37 to the bore 17 and from the bore 17 through the openings 18 to the grooves 16.
  • the two spinning solutions exit from the grooves 16 as conjugate or composite filaments.
  • the pipe 37 is threaded into the tubular insert 11 and extends through a bore 38 in the plate 22 to interconnect the bore 17 with a manifold opening 31.
  • the upper end of the pipe 37 is threaded, a nut 40 being provided on the upper end of the pipe 37, for pulling the upper end of the tubular insert 11 up tight against the lower surface of the plate 22.
  • a gasket 41 beneath the nut 40 serves to prevent leakage from one manifold opening into the other.
  • FIGURE 2 While only a single insert 11 is shown in FIGURE 2, it is to be understood that the apparatus may include a large number of these manifolds. Inasmuch as the diameter of the insert 11 may be as small as A" or less, quite a number of these inserts will occupy only a small space. Thus, this spinning apparatus, in addition to being simple and easy to fabricate is capable of producing a large number of conjugate filaments.
  • the apparatus can quickly be disassembled for repair or inspection. In case of wear or damage to one of the inserts 11, that particular insert can be quickly replaced without a longdown time.
  • An apparatus for spinning filaments comprising a plate having therein a bore, an insert mounted in the bore and having in the periphery thereof a plurality of spaced longitudinal grooves extending the length of the bore, the grooves and the wall of the bore defining spinning orifices, means attached to the plate defining a first manifold opening surrounding the insert and leading to the grooves therein, said insert having therein a central bore and a plurality of openings leading from said central bore to said grooves, said openings intersecting said grooves at points within the bore in the plate, and means defining a second manifold opening connected to the central bore in the insert.
  • An apparatus for spinning filaments comprising first, second and third plates; means for supporting the plates in a stacked relationship and for forming a first manifold between the first and second plates and a second manifold between the second and third plates; said first plate having therein a plurality of spaced bores; a plurality of inserts extending from the second plate into and through the bores in the first plate and having therein central bores and also having in the surfaces thereof a plurality of spaced longitudinal grooves; and said grooves and bores defining a plurality of spinning orifices; each said insert having a plurality of passageways interconnecting the central bore and the longitudinal grooves; and means for securing the inserts to the second plates; said second plates being apertured to connect said central bores to said second manifold.
